LIQUID-COOLER.

7Specification of Letters Patent.

Application filed April 1, 1909. Serial No. 487,167.

To (LLL whom 'it may concern:

Be it known that l, JoHN D. HENDRIX, a citizen of the United States, residingat Atlanta, in the county of Fulton and State of Georgia, have invented new and useful Improvements Vin Liquid-Coolers,"of which the following is a specification.

This invention relates to liquid coolers, the object ofthe invention being to provide a refrigerator or cooler especially adapted for beer and like beverages, the construction allowing the beer or other beverage to pass in a circuitous way through the body of the cooler andA be subjected to the cooling influence of the ice or other refrigerating medium contained in the body of the cooler without such liquid coming in contact with the refrigeratingagent.

A further object of the invention is to provide a cooler of sectional construction, the parts of which are so combined as to enable them to be easilyand quickly disassembled for the purpose of thoroughly cleansing the channels and various portions of the passages through which the beveragecourses in its travel from the inlet to the outlet, thus rendering the device sanitary.

A further object of the invention is to provide a cooler of the class described with means whereby a portion of the air may be extracted from the refrigerant compartment. Wlth the above and other lobjects in view, the nature of which will more readily appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanying drawings Figure 1 is a side elevation, partly broken away in section, illustrative of the improved cooler.`

Fig.4 2 is a vertical diametrical section through the same taken in line with the inlet and outlet. Fig. 3 is a side elevation partly in .diametrical section through the upper portion of the outer shell. Fig. t is a plan view of the cooler with the top cap nemoved.V

Fig. 5 is a horizontal section through the cooler. Fig. 6 is a detail plan view of the locking ring or nut.

Referring to Figs. 1 and 2, the main body of the cooler is seen to comprise an'outer cylindrical shell 1 and an inner shell 2 having g a general cylindrical shape but corrugated or fluted spirally to' form a spiral conduit or liquid passage 3 extending continuously and unbroken from one end to the other of the shell 2 with the outwardly extending ridges 4 between which the grooves 3 'intervene, touching Aor lying in close contact with the inner wall of the outer shell 1. The inner shell 2 is connectedby a liquid-tight' joint at the bottom edge thereof and with al cup-shaped base 5, the saidibase being provided within its outer marginal edge with a concentric flange 6 which acts as a centering rest for the outer shell l, the said outer shell fitting around the flange 6 as shown in Figs. 1 and 2. The outer shell 1 has secured to its lower edge and upon its outer side, an

angle iron ring 7 forming a iange between in the upper portion of the shell 1 where it is provided in its inner face with agroove in which is seated and held a gasket 12 adapted to be pressed into firm contact with theouter surface of the neck 10. The gasket. 12 is pressed against the neck 10 by means of a gland 13 above which is arranged a threaded ring or nut 14 screwed upon the threaded upper portion of the neck 10 as sho-wn in Figs. 1 and 2, the said nut being providedat suitable intervals with Spanner sockets 15 to enable said ring or nut to be tightened or loosened. On the upper end of (the neck 10 there is screwed an internally desired amount of air to be exhausted from the interior of the body of the cooler.

The cup shaped base 5 is formed with acircular outlet channel 21 formed by offsetting inwardly a portion of the periphery or rim thereof as clearly shown in the .diametrical section, Fig. 2. In like manner the neck 10 is inwardly oilset to forman. an-

' Patented Nov. ,2, 19012 nular inlet chamber 22 into which the beer lor other beverage is led by means of an inlet nular outlet channel 21 is an outlet connection '24. The inlet and outlet connections and 24 may be attached to the outer shell 1 in any convenient manner.

The liquid entering through the connection 23 passes around the circular inlet channel 2Q and is t-hence directed in al spiral course between the outer and inner shells l and 2, until it nally reaches the circular outlet channel 21 from whence it passes through the outlet port 24 to the point of delivery. The interior or main body of the cooler is designed to be filled with ice or retrigerating medium and thus the liquid or beverage is subjected for a considerable length of time to the cooling influence of such agent. In addition to this the outer and inner shells may be readily separated yby removing the cap 16 and the nut 14 and drawing the inner shell downwardly through the bottom of the outer shell. The parts may be then thoroughly cleansed and readily reassembled for further use. By eX- hausting a portion of the air from the central refrigerant chalnber from time to time, the refrigerating agent is prevented from melting too rapidly.

I claim 1. A cooler for the purpose specified comprising an outer cylindrical shell, an inner shell having a spirally corrugated body of such diameter that the outwardly extending ridges of the corrugations bear against the inner wall of the outer shell to form a spiral passage way between the outer and inner shell, a cup-shaped base at the lower end of the inner shell flanged to overlap the bottom edge of the outer shell, a neck at the upper end of said inner shell, and means for producing a tight joint between the upper portion of the outer shell and said neck consisting of a gasket holding ring, a gland, and a threaded ring or nut screwm around said neck, substantially as describe 2. A cooler for the purpose specified comprising an outer cylindrical shell, an inner spirally corrugated shell the outwardly extending ridges of which lie in contact with' the inner surface of the outer shell, a cupshaped base secured to the lower end of the inner shell and having the outer body portion or rim thereof inwardly oifset to form an annular outlet channel, and a flange which overlaps the bottom edge of the outer shell, an outlet connection communicating with said outlet channel, a neck at the opposite end ot the inner shell reduced in diameter to form an annular inlet channel, an inlet connection leading to said channel, and means forA producing a tight joint between the outer shell and said neck consisting of a gasket-holding ring on the outer shell, a gland embracing the neck, and a nut screwing upon said neck and coperating with the gland, substantially as described. i

3. A cooler for the purpose specified comprising an outer cylindrical shell, an inner spirally corrugated shell the outwardly extending ridges o whichlie in contact with the inner surface of the outer shell, annular inlet and outlet channels arranged at opposite ends of the spiral passage-way thus formed between the two shells, inlet and outlet connections leading to said annular channels, joint-forming means for effecting a liquid tight connection between said shells at or near the opposite ends thereof, a permanent closure for one end of the inner shell, and a detachable closure for the other end of said shell, the joint forming means at one end of the cooler being removable to permit the shells to be separated one from the other.

In testimony whereof I atl-'1X my signature in presence of two witnesses.
